Lent and borrowed stock

Shops lend each other goods until Monday. Record it in Inventory → Lent & borrowed so the shelf count stays honest.

• Lend out: the product, how many, the location, the other business's name and phone, a back by date. The stock leaves your shelf at once.
• Borrow in: the same the other way. Their goods on your shelf sell like your own.
• Take back some or all of it. A late loan is marked.
• They keep it / We keep it closes the loan; then record the sale or purchase yourself at the price you agree.

A product's history reads "Lent to Hodan Shop" and "Back from Hodan Shop".

Reports → Inventory → Stock by Day shows, for any period and location, each product's Opening, sold, returned, received, transferred, adjusted, made, lent or borrowed, and Closing. The columns always add up; a row opens the product's movements.
